Laboratory Acoustics / Noise Control

We want to promote an acoustic environment, which contributes to a high quality of life.

As the leading Swiss acoustic competence center we contribute to noise control and design of the acoustic environment on a technical-scientific level. We expand the state of knowledge on an international level and help to put it into practice.

Our focus lies on the following fields of environmental and architectural acoustics:

  • Outdoor sound propagation
  • Noise control at the source
  • Sound transmissions in buildings and rooms

On a high scientific level we work interdisciplinary together with national and international partners (e.g. researchers on the effect of noise on man). We transfer our knowledge to the society. Together with industry partners we develop marketable innovations.

Areas of activity of the Acoustics / Noise Control Laboratory

In the Materials and Systems Group, one area in which we concentrate our activities (among others) is the reduction of radiated sound and the transmission of noise and vibration. Here we deal primarily with the transmission of sound in lightweight constructions and assemblies which we are able to study in our new test facility. In our Building Acoustics Laboratory we undertake acoustic investigations of the highest quality in accordance with international scientific and technical regulations.

The propagation of sound outdoor and the characterization of technical sources of noise form the focal point of our activities in the Environmental Acoustics Group. We develop calculation methods which take into account the effects of weather conditions on sound propagation outdoor and increasingly integrate into the process the exact solution of the wave equation. We (further) develop and use new methods for the characterization of noise sources such as road, railway and aircraft traffic, etc. The method of calculating aircraft noise developed by the Acoustics / Noise Control Laboratory is currently permanently in use for the study of noise emissions in the vicinity of airfields and airports.
